"While the button to activate the hands-free caused us some frustration due to its size, the hands-free performance was good. Callers could hear us clearly until we turned onto a windy street. At that point, our voice became slightly harder, but not impossible, to hear. Thanks to the headphones, we had no problems hearing our callers, even with the wind blowing.
Ultimate Ears' super.fi 4vi earbuds are a solid investment for audiophiles on a budget and iPhone fans who want excellent sound quality combined with hands-free functionality."
